But if you buy a fucking buggati cost 900 thousand maybe the lowest price anda police dont care... Anda this mazda have the same hp then bugatti...

364 days later, you're at sema with your own 4 rotor, running and driving. It's been awesome watching over the last year or couple years +. Maybe within the next couple weeks or months itll be yours on the dyno providing unlimited eargasms. Thanks for being crazy, Rob, we all appreciate and love it and you.
The rx7 is legendary when it actually runs. That said, if you have time and patience, as well as funds, it may be the perfect car for the jdm Enthusiast!
vullut The FD weighs nearly 1.3 tonnes. I ran mine at 430whp it was a good happy medium for a 13b, it was fast, fun and manageable.. If you go for much more power, You're getting into the territory of big laggy turbos, and RX-7s need all the low end power you can get since it has about as much torque as a pensioner with arthritis operating a screwdriver.
Officer: Is that a turbo popping out the hood?? Rob: Nope, just a cooling fan. Kinda hot summer isnt it. Officer: and what about your running laptop on the passenger sit? Rob: thats what the cooling fan is for!

@@DocRammstein "Ohh but dude, just wait until the V-Tec kicks in!" Lol. What a running joke from over a decade ago. I think even a Prius comes with variable valve timing these days. Lol
Still my favorite modded car! Years later and I watched this video a 100 times by now and still can't get enough of it!😂 And I always watch it with a subwoofer and high volume so I can hear and feel it rumble at low rpm!
I can't wait to turn the key on my 26b RX7, been working on it since 2006. It was 20b (3 rotor) now I am selling everything and moving to a 4 rotor. That sound!!! I can't wait. I'm doing a compound setup. Pro-charger feeding into a 80mm turbo. As soon as my RB30/26 Skyline R33 GTR Vspec is completed, I'm jumping back on the 4 rotor.
Here after watching Rob's pull on his 4 rotary. To put this into perspective, this car was 958hp at 560fpnds of tourqe on rear wheel drive. Rob's is 1020hp at almost 800fpnds of tourqe on all four wheels. Thats alot alot alot of extra tourqe the knew Bugatti Veyron sport that has a w 16 in it has 1000fpnds of tourqe.
Ever since i seen this car 5 yrs ago. I been in love with it. This dude is a fuhkin mad man and should be locked up in the funny house😂😂. And then got the nerve to have a smile on his face like shyt funny, sir do you realize the beast you built!? This type of shyt is not no game 😂
This stuff is awesome, I'm glad there are people willing to film it and share it with us. Before UA-cam I didn't even know this type of stuff even gets done, dyno-ing and dialing in custom built cars to this level, definitely doesn't happen around these parts of the world where most people can barely afford their econoboxes and the people that do mods stop at bolt-ons and replace the engine if something goes wrong. Heck, before UA-cam I didn't even know they made stronger aftermarket internals for production engines, or that a damaged head can be resurfaced by a machinists shop. Where would I be able to learn about these things, mechanics school? That place would say don't touch anything that's not oem because "the factory that made the engine knows best and makes the best possible parts to work with the engine they made" or some nonsense like that. Plus that I can't stand being in school and forced to do stuff that I don't want, glad that's over. Like this I can enjoy the videos and learn things along the way. It's not like I can go to a track and ask the owners of custom built cars what they did to their cars and hang around at their shop to learn since this sort of stuff doesn't happen around here, I've never seen a dragstrip aside from UA-cam. And even if there were such a thing around, it would be nothing like this level, just a regular tuning shop, what would be the chance they would let a random nobody hang around and learn about what they do. Plus my health and other things like earning a living wouldn't allow me to be there nearly as much as I would like. So yeah, I am grateful to all these people that take the time to show others how they build custom cars, share tips and tricks and teach others how they do things. And not just in cars but in many other subjects, like electronics, computers, mechanics and many more. I learned more from BigClive and Ave than I did getting my electrician diploma. And the likes of Finnegan's garage, motortrend before they went off UA-cam, Brent from Pfi speed, Jeremy at Fasterproms and so many more I learned things from, these being a small fraction of the channels I watch, it would take ages to list them all. Years of watching things on UA-cam also greatly helped with my English as it is not my native language and without this, games and spending my time figuring out how to use computers, after finishing school I know that I wouldn't of been able to even piece together sentences, like almost all of my schoolmates, unless you have your own activity that makes you deal with English or really wish to learn it, what they do in school is literally useless as almost no one actually learns anything. Forcing people to learn about a language just because "you have to if you want to pass" does not work. They should motivate the students by telling them something like "don't you want to be able to communicate with people anywhere you go, or watch movies without needing subtitles, what if there aren't any for that thing you wan to see, etc, well if you do you should look into this" being fluent and speaking correctly in a foreign language is a really hard thing to achieve, but you don't need that to understand people, communicate and get great usefulness out of it. I got extremely carried away but don't feel like deleting most of this comment as it took a long time to write and has a meaning. But yeah, Thanks for making it possible to see these things without being there, someone from the other side of the globe appreciates it, seeing some of these things is really inspiring. Waiting to see your 4 rotor come to life Rob.
If you are located in America I would definitely recommend checking out the school of automotive machinests in Houston Texas, aka SAM tech. Very cool school and the only one of its kind to my knowledge.
michael capps I sadly am not In America, as I say in my comment my native language is not english, I am from eastern Europe, not the greatest place to be if you want to mess with cars.
That thing is a monster. Dont really know the fully potential of the steering and handling but it looks like that thing will crush anything on the track.
Well the big difference between them and this dude they actually work on rotary shit seems like he’s not doing a damn thing and somehow is a rotary god🤔 i never see this dude working on anything either way
It always amazes me how one can know how to make a build like this. How to come up with all the customizations, figure out how to design everything to fit properly, get the desired outputs, engine sounds, gearbox timings, pressure values, cable and tube management, body work. Just making everything fit and work as you imagined it. You need to know everything there is to know about every part and details of a car and engine, every limit and possibility etc to know exactly how to make everything work. There's nothing conventional about this. It's all about pushing boundaries and think outside the box. Anything is possible if you know the ways around it, and to know that shit blows my mind. It's like science and chemistry. It's hard enough as it is and not all people can be a scientist or lab professor. And after years and years of learning, understanding and research you can start manipulate the elements when you know all the do's and dont's like what goes into what and with what or should work with some changing to the variables, what's too much or too little, break everything down and apart to explain every step of a reaction process from one form to another like it's common knowledge... To me builds like this is like that 1% shit what has no drawing where everything is logically planned out for anyone to follow if you just have the tools, materials and handy skills. Like building a house, anyone can do it with a little experience with building. But this is not by the book like "How to build a 1000 hp drift car". This is your imagination and how to apply it in reality using extreme means. This level of customization is like that difficulty in games where it says you won't make it unless you're a professional pro xD Not just live for it, but so addicted that a social life outside the community doesn't exist. Where the regular pro goes "That's taking it too far man". I mean I've seen custom builds with jet engines like how the hell does anyone come up with that idea and then how to make it work in a street car?? You pretty much need to make all the part yourself because you can't find those when shopping for car parts online or at the store.
I never knew you guys met. I always wanted to see a collabo between you too. Aaron Parker, Dahm, & Mazzei in one video ? Thats an all star cast for me.
@@09hahug The hell are you talking about? Even with their “freedom,” most women outright refuse to do this work, can’t hack it, or have no interest in it. That’s fine. Women and men are different, and they think differently. Engineering is a result of the architecture of the male mind; it is natural that the vast majority of females would not find it appealing.
Yeah more torque but never be Stronger this Rotor engines you servecing every 2000miles all Hardware need to repair .... the Price of this High Rotating rpm and more than 20PSI are critical ...20PSI is nothing for a 2Jz or Audi 5Zylinder Turbo they are Laughing and scream give me more
butch t Japan has had ridiculously time attack cars since years ago. I don’t remember if this rx7 was 3 or 4 rotor but it was making like 500 allmotor and was insanely fast on the track.
I run the car maintenance UA-cam channel in Korea. I'm always learning such a great ideas on your channel. I hope we have a chance to be together. Thank you.
I am saving this video for that engine sound fix. You can see the tires smoking on the Dyno ... I am in Love with this Build. Who is that insanely beautiful master mechanic geesh
I imagine that with some adjustments, that LACK of drivability can be cured. I was kinda disappointed to see how jerky and “cough, spit, puke” it acted. Still cool, just room for improvements!
@@duanebailey6253 This is a peripheral port 4 rotor, as in the intake ports go straight into the rotor housings, unlike the Mazda side port intake design that runs through the irons into the rotor housing creating a smooth idle. Peripheral ported motors are notorious for being pigs, and only want to work at full throttle. My brother used to have a peripheral ported NA 13B in an Rx2 sedan, it's was a lot of fun to drive, but was wild to try and drive on the street, very hard to tame a Peripheral port, Abel has done a good job here. I think Robs motor is side ported, like Mad Mike Widdett's 26BTT Mx5 drift car.
For the sake of the all time great !!! R26B engine please stop comparing. R26B: different housings Different rotors Runs 3 spark plugs per housing, Has indipendent throttle body's per housing, The housing where re surfaced with specially engineered alluminium to handle the rev range, The eccentric shaft is different, The centre plates where specifically designed to handle the twist incase of backfire and most importantly can rev to 11000 rpm all day of the week generating 900hp. Congratulations it's a great achievement!!! But to come to the conclusion that you can slap together a 4 rotor and compare it to the mechanical engineers at Mazda who spent years of R&D is just a slap to the face for all of us Rotary fans and more importantly the legendary!!! (787B).
Idk why but I was expecting this to make more torque? Regardless 950hp/650tq to the wheels is absolutely INSANE! And anyone questioning Rob's choice in turbo size [in his 4-rotor] simply doesn't understand the volume of air being pumped out of a 4-rotor engine. And the graph proves it! Just look at how beautiful that curve is!? Even with that dinner-plate-sized turbo! WOW!!! Rotary FTMFW!!!
@@chasethompson7392 yeah ig kinda true. But they dont do emissions test. The only law on sound is that the exhaust system must contain 1 muffler at least.

Years of watching things on UA-cam also greatly helped with my English as it is not my native language and without this, games and spending my time figuring out how to use computers, after finishing school I know that I wouldn't of been able to even piece together sentences, like almost all of my schoolmates, unless you have your own activity that makes you deal with English or really wish to learn it, what they do in school is literally useless as almost no one actually learns anything. Forcing people to learn about a language just because "you have to if you want to pass" does not work. They should motivate the students by telling them something like "don't you want to be able to communicate with people anywhere you go, or watch movies without needing subtitles, what if there aren't any for that thing you wan to see, etc, well if you do you should look into this" being fluent and speaking correctly in a foreign language is a really hard thing to achieve, but you don't need that to understand people, communicate and get great usefulness out of it. I got extremely carried away but don't feel like deleting most of this comment as it took a long time to write and has a meaning. But yeah, Thanks for making it possible to see these things without being there, someone from the other side of the globe appreciates it, seeing some of these things is really inspiring. Waiting to see your 4 rotor come to life Rob.
Good luck in your adventures. Sounds like you have ambition. That alone can take you anywhere.
If you are located in America I would definitely recommend checking out the school of automotive machinests in Houston Texas, aka SAM tech. Very cool school and the only one of its kind to my knowledge.
Twistin' Props Thanks for the kind words sir.
michael capps I sadly am not In America, as I say in my comment my native language is not english, I am from eastern Europe, not the greatest place to be if you want to mess with cars.
Sounds like a freaken race sled
Amazing!
Might have to look into building one of these cars.
Good luck finding one with a half way decent engine doing a ls swap on the fukers are hard and just not worth the truble in my opinion
Ok. I don’t care who’s 4 rotor it is. LET ME SEE IT ALL PLZ ITS SO AMAZING
Check Davids channel you'll not be disappointed
Hoonigans also looked at the car during their Sema special
Sounds like either your best dream or worst nightmare, depending on if you're driving it or racing against it. Incredible
That thing is a monster. Dont really know the fully potential of the steering and handling but it looks like that thing will crush anything on the track.
That is if it runs
it will run out of fuel before it will cross the line 🐒
Dude you need to make an NA 4 Rotor. IMAGINE THE SOUND!
it already exists, its called Mazda 787B

So between Rob Dahm and the Vargas brothers, I'm getting more and more tempted to sell my soul to the rotary lords.
If there is any doubt left search out Mad Mike Haha
Well the big difference between them and this dude they actually work on rotary shit seems like he’s not doing a damn thing and somehow is a rotary god🤔 i never see this dude working on anything either way
Pac Performance is the real rotary GOD, untill I get enough $ to design my own engine :D
@@Dthejewl Correct, Mad Mike only drives rotaries. Promaz builds hes engines.

One of the beautifullest cars i have ever seen in my life. Wonderful. Come to germany an drive it on the german autobahn.....
It always amazes me how one can know how to make a build like this. How to come up with all the customizations, figure out how to design everything to fit properly, get the desired outputs, engine sounds, gearbox timings, pressure values, cable and tube management, body work. Just making everything fit and work as you imagined it.
You need to know everything there is to know about every part and details of a car and engine, every limit and possibility etc to know exactly how to make everything work. There's nothing conventional about this. It's all about pushing boundaries and think outside the box. Anything is possible if you know the ways around it, and to know that shit blows my mind. It's like science and chemistry. It's hard enough as it is and not all people can be a scientist or lab professor. And after years and years of learning, understanding and research you can start manipulate the elements when you know all the do's and dont's like what goes into what and with what or should work with some changing to the variables, what's too much or too little, break everything down and apart to explain every step of a reaction process from one form to another like it's common knowledge... To me builds like this is like that 1% shit what has no drawing where everything is logically planned out for anyone to follow if you just have the tools, materials and handy skills. Like building a house, anyone can do it with a little experience with building. But this is not by the book like "How to build a 1000 hp drift car". This is your imagination and how to apply it in reality using extreme means. This level of customization is like that difficulty in games where it says you won't make it unless you're a professional pro xD Not just live for it, but so addicted that a social life outside the community doesn't exist. Where the regular pro goes "That's taking it too far man".
I mean I've seen custom builds with jet engines like how the hell does anyone come up with that idea and then how to make it work in a street car?? You pretty much need to make all the part yourself because you can't find those when shopping for car parts online or at the store.
Lmao ur mom
I never knew you guys met. I always wanted to see a collabo between you too. Aaron Parker, Dahm, & Mazzei in one video ? Thats an all star cast for me.
It was nice to see that young lady working on the car. You don't see very much of that nowadays. Kudos to her.
Rakin Will The f*** you talking about? You wouldn't even let them leave the kitchen back in the day. This is progress.
@@09hahug but I was more attracted to the more feminine women
Amen we need more skilled ladies.. my auto tech program graduated less than 5 out of over 100 total students.
69th like :)
@@09hahug
The hell are you talking about? Even with their “freedom,” most women outright refuse to do this work, can’t hack it, or have no interest in it.
That’s fine. Women and men are different, and they think differently. Engineering is a result of the architecture of the male mind; it is natural that the vast majority of females would not find it appealing.
this is my favourite video on youtube
Just Dropped out of school so I could hear this
Nigga what about putting this engine in the Z...
Juim 1j ayyy that’s not a bad idea squad lol
Your videos are classic. I used to laugh so hard watching your vids repeatedly.
David Li 😎 the good ol days
Use to be Mazda tech when rotary came out didn’t look or run like that. Nice job guys
Teach me
Charlotte Petrie you’re fine
DAMN!!!!! by far the best looking and sounding rx-7 I've ever seen!!
He's obviously a very skilled CAR builder..this is what perfection looks like. 💪❤
F1 and 787B:
Who are you?
This modification:
*I am you,but stronger.*
@ryo ga it's a mod
Easily poured six figure into that build.
Here my friend, it is louder than you can imagine. These 30 seconds are far better than what is shown here. ua-cam.com/video/sxXtpMngivM/v-deo.html
@@harinand9762 Nah that’s way too much. But it’s definitely a hefty 5-digit, not including the car
Yeah more torque but never be Stronger this Rotor engines you servecing every 2000miles all Hardware need to repair .... the Price of this High Rotating rpm and more than 20PSI are critical ...20PSI is nothing for a 2Jz or Audi 5Zylinder Turbo they are Laughing and scream give me more
Omg, that sounds NASTY! Absolutely incredible.
that girl is no joke
mirrorino the car or the woman?
@@ayle1312 Both
Luuk Willems
yes
i love that she doesnt even take the ring off
She's got a gut and an ugly face under eight pounds of makeup and implants. I'll pass.
the fact that his shop was right down the road from my house and daycare for years is insane
Congratulations!!!! You have the best car in youtube, hands down.
I still think it's funny how all 3 of the rotary gods are in this video. (David Mazzei, Rob, and Aaron Parker)
This has got to be the meanest rx7 right now until rob's 4 rotor awd be completed.
Not even close. It has done nothing to prove it's self and the drivability is trash hesitating at part throttle.
MSengineering David is that even english?
butch t Japan has had ridiculously time attack cars since years ago. I don’t remember if this rx7 was 3 or 4 rotor but it was making like 500 allmotor and was insanely fast on the track.
preludeF20Bking white fd3s? It’s a 4 rotor.
Robs awd 4 rotor___ coming soon to a dyno near you november 2028
Cool ass car I had to stop and check it out wow I feel the adrenaline running just looking at it
I run the car maintenance UA-cam channel in Korea. I'm always learning such a great ideas on your channel. I hope we have a chance to be together. Thank you.

Mazda 787B: *THAT'S MY SON!!! I'M SO PROUD OF YOU!!!!* :'D
0:50 I like how auto subtitles detected the rx7's sound like a [music]
cuz it is
This is the shit we want to see Rob, also ... WHERE IS THE 4ROTOR ROB ?!
noWie won’t be seen again till 2 weeks before sema next year knowing rob 😂
2028
I am saving this video for that engine sound fix. You can see the tires smoking on the Dyno ... I am in Love with this Build. Who is that insanely beautiful master mechanic geesh
I imagine that with some adjustments, that LACK of drivability can be cured. I was kinda disappointed to see how jerky and “cough, spit, puke” it acted. Still cool, just room for improvements!
Im wrong it wasnt DBW. sounded fine going in so im guessing something melted or was faulty.
@@duanebailey6253 This is a peripheral port 4 rotor, as in the intake ports go straight into the rotor housings, unlike the Mazda side port intake design that runs through the irons into the rotor housing creating a smooth idle. Peripheral ported motors are notorious for being pigs, and only want to work at full throttle. My brother used to have a peripheral ported NA 13B in an Rx2 sedan, it's was a lot of fun to drive, but was wild to try and drive on the street, very hard to tame a Peripheral port, Abel has done a good job here. I think Robs motor is side ported, like Mad Mike Widdett's 26BTT Mx5 drift car.
You have to use a tad more throttle to smooth out the overlap, the driver wasnt used to it at low rpm
David commented, but I was just about to say the driver wasn’t use to driving this transmission, it’s never jerky when David drives it
Mazzei Formula ....that crossed my mind too!😉
Holy shit! Is that Abel Ibarra? What a legend in the rotary community. I remember him from the 90's when import drag racing was huge.
For the sake of the all time great !!! R26B engine please stop comparing.
R26B: different housings
Different rotors
Runs 3 spark plugs per housing,
Has indipendent throttle body's per housing,
The housing where re surfaced with specially engineered alluminium to handle the rev range,
The eccentric shaft is different,
The centre plates where specifically designed to handle the twist incase of backfire and most importantly can rev to 11000 rpm all day of the week generating 900hp.
Congratulations it's a great achievement!!! But to come to the conclusion that you can slap together a 4 rotor and compare it to the mechanical engineers at Mazda who spent years of R&D is just a slap to the face for all of us Rotary fans and more importantly the legendary!!! (787B).
Abdallah Elhassan Do you feel better now?
I get the feeling you overestimate engineers
But it's missing pistons bro!
This thing should be featured in The fast and the furious, hands down, what a machine
Idk why but I was expecting this to make more torque? Regardless 950hp/650tq to the wheels is absolutely INSANE! And anyone questioning Rob's choice in turbo size [in his 4-rotor] simply doesn't understand the volume of air being pumped out of a 4-rotor engine. And the graph proves it! Just look at how beautiful that curve is!? Even with that dinner-plate-sized turbo! WOW!!! Rotary FTMFW!!!
The most legendary rx7 video even after years
I love how the auto captions call the 4 rotor running, [music]. Without a doubt. It is singing.
Luckily in Alabama we have no laws on emissions or sound!
Really? You got to be fucking kidding.
Cries in german
Welp, guess I'm moving to alabama
Well we technically do but nobody cares lol
@@chasethompson7392 yeah ig kinda true. But they dont do emissions test. The only law on sound is that the exhaust system must contain 1 muffler at least. I did research recently before my brother and I put in equal length headers in his e46. Its straight piped with only one muffler all the way. If you wanna see you can check out his video on it, just search " ddtropical bmw e46 330i " on youtube and its the one uploaded by DDtropical
In Montana we have non at all
This car is sick and awesome to see rotors making a comeback.
Wow great stuff folks, love mazdas especially hyundais
